OBJECTIVES: Several animal studies have shown that bladder performance improves as a result of diuresis. Whether increased urine output also has beneficial effects on elderly male bladder function and lower urinary tract symptoms is unknown. METHODS: We performed a randomized placebo-controlled trial of 141 men, 55 to 75 years of age, with moderate lower urinary tract symptoms. The experimental group drank 1.5 L of extra water daily. The control group consumed one tablespoon of placebo syrup daily. After 6 months, we evaluated bladder contractility, voided volumes, and the severity of lower urinary tract symptoms. The actual increase in water consumption was measured using the deuterium urine dilution method. RESULTS: Water consumption in the intervention group increased by 359 mL (95% confidence interval [CI] 171 to 548) per 24 hours compared with the control group. At 6 months, no statistically significant effect was found in the maximal flow rate (0.9 mL/s, 95% CI -0.4 to 2.2) compared with placebo. A statistically significant effect was found for bladder pressure (20 cm H2O, 95% CI 6 to 34) and bladder wall stress (1.9 N/cm2, 95% CI 0.3 to 3.5). In addition, it showed that the experimental group had greater maximal (44 mL, 95% CI -1 to 90) and average (26 mL, 95% CI 1 to 51) voided volumes per urination. The subjective effect parameters improved in both groups, but no statistically significant differences were found between the two groups. CONCLUSIONS: It seems possible to improve some aspects of male bladder function by drinking more water. However, the effects are too small to be clinically relevantCoping and quality of life in relation to headache in Dutch schoolchildrenhttp://repub.eur.nl/pub/57246/

The aim of this study was to describe the Quality of Life and pain coping strategies of school children in relation to headache severity. We conducted a cross-sectional study in 2815 children between the age of 9 and 17 years, who filled out Waters' Headache Questionnaire (WHQ), the Paediatric Pain Assessment Tool (PPAT), the Quality of Life Headache in Youth (QLH-Y) questionnaire and the Pain Coping Questionnaire (PCQ) in the class-room setting. Weekly headaches were reported by 22% of the sample. Low, medium, and high headache severity groups were constructed, based on headache frequency, duration and intensity criteria. Results show that children with the highest headache severity report the lowest Quality of Life in general and the lowest Quality of Health, as well as the most problems with regard to physical functioning, impact of headache on daily and leisure activities, physical symptoms other than headache, and social functioning at home. With regard to using pain coping strategies, children with the most severe headaches seek more social support, they internalize and externalize more, they use less behavioural and cognitive distraction techniques, and seek information less.Recurrent headache, coping, and quality of life in children: A reviewhttp://repub.eur.nl/pub/64572/
